Noun Clauses in English: When a Clause Is Used as a Noun in English
Noun clauses are clauses that function as nouns. A clause is a group of words containing a subject and a verb. A noun is the name of a person, place, thing, or idea. In this posting I talk about how to form and correctly use noun clauses. I include many example sentences. The download at the end will give you additional practice using noun clauses.
What is a noun clause?
A noun clause is a clause that functions as a noun. Noun clauses are dependent clauses. They cannot stand alone and need to be part of an independent clause to form a complete sentence. Noun clauses can be used in the same way as nouns. This means they can be subjects, objects, or complements in a sentence.
Noun clauses as subjects
Noun clauses are often used as subjects of sentences. Look at this sentence:
The subject of the sentence is the pronoun something. Now let us look at the sentence with a noun clause replacing something.
What he said is a noun clause. He is the subject of the clause and said is the verb. What he said is the subject of the sentence.
Noun clauses as objects
Noun clauses can be direct objects and objects of prepositions. Look at this sentence:
Something is the direct object of the sentence. Now look at the sentence with a noun clause replacing something.
That she was tired is the direct object of the sentence. Note that we can reduce this clause by omitting that.
Now look at this sentence:
Something is the object of the preposition about. Here is the sentence with a noun clause in place of something.
What he thinks is the object of a preposition. If we reduce the clause by omitting about, we have:
Noun clauses as complements
We use complements with be verb. Look at this sentence:
In this case, something is the complement of the sentence. Now let us look at the sentence using a noun clause:
That my boss can’t make a decision is a complement, as it means the same thing as problem.
Phrases that signal noun clauses
Below are some common phrases that signal that a noun clause may be coming.
- I don’t know if he got my email.
- I can’t remember who finally solved this problem.
- Please tell me when the party starts.
- Do you know who is teaching this class?
- I wonder if she will be at work today.
- I think that it’s my turn to drive tonight.
In all of these sentences, the noun clause is the direct object of the sentence.
Common noun clause markers
The words below are called noun clause markers. These words introduce noun clauses. You will notice that some of these words are question words. Note that even when a question word introduces a noun clause, we do not invert the subject and the verb of the noun clause. We use the normal subject + verb order. This is because these clauses are not really questions. They are statements.
- how–I’ll never understand how he did that! (direct object)
- that—That he found a good job is amazing. He never even finished high school! (subject)
- what–She doesn’t think about what anyone else needs. (object of a preposition)
- whatever–You can order whatever you want from the menu. (direct object)
- when—The decision to make is when we are going on vacation. (complement)
- where–Please tell me where he is going.
- whether (or not)–He didn’t tell me whether (or not) he would be late today. (direct object)
- which–I don’t know which location Bob prefers. (direct object)
- whichever–I’ll support whichever decision you make. (direct object)
- who–Do you know who our new boss is? (direct object)
- whoever—Whoever broke into my house has not yet been caught. (subject)
- why–I don’t know why he quit his job. (direct object)
- if–Tell me if I can borrow your car tomorrow.
You now know that noun clauses can be used a subjects, direct objects, objects of prepositions, and complements in sentences. Noun clauses often follow certain phrases. We also introduce them with certain words or markers. The word order in a noun clause is always the normal order of subject + verb, even if the noun clause begins with a question word. The download will give you more opportunities to practice understanding and using noun clauses.
